In use, the brush is held by the lingers of the right hand in pencil fashion, t e dior lcharge of air and color being ntrolled by operating the lever 39 with t e index finger.

If now t e o erntor tilts the portion 40 rearwardly e nozzle Q3 will he slid forwardly to uncover the opening 29, whereupon the suction of 'the air blast I and the tip of the nozzle 23 causes s ow of eolor from the bottle 27 through the tube the' needle 20 and the annular space botween the forward ends of the needle and the nozzle 23.

The means herein shown for reciprocating the nozzle 23 to open and close the color discharge comprises a spring 30 surrounding seid nozzle and interposed between shoulder 31 in the sleeve 17 and one side of an annularjange 32 on the nozzle.
